remember
[tex] \frac{xyz}{abc}=( \frac{x}{a} )( \frac{y}{b} )( \frac{z}{c} ) [/tex]
and
[tex] \frac{x^m}{x^n}=x^{m-n} [/tex]
split them to have same bases
[tex] \frac{12^32^24^4}{4^32^112^2}=[/tex]
[tex]( \frac{12^3}{12^2} )( \frac{4^4}{4^3} )( \frac{2^2}{2^1} )=[/tex]
[tex](12^1)(4^1)(2^1)=[/tex]
[tex](12)(4)(2)=[/tex]
[tex]96[/tex]
